Description du poste

SFEIR BELGIUM - AI Engineer - Become an Augmented Expert

Brussels | Startup Spirit | AI‑Native Group

Sharp Tech. Real Impact.

Who are we?

SFEIR is a technology innovation catalyst at the forefront of the AI revolution. We transform organizations by creating tangible, lasting impact – not by following trends, but by industrializing them alongside our clients.

Our belief: well‑orchestrated agentic AI enables massive acceleration across delivery cycles. The organizations that will pull ahead won’t be those that adopt AI the earliest, but those that industrialize it with method. That’s exactly what we do through our Context Engineering approach, our partnership with Anthropic, and our GenAI platform RAISE.

Key figures

• 950 consultants passionate about tech and augmented by AI
• 8 offices across France, Luxembourg, and Brussels
• Anthropic Select Partner within the Services track of the Claude Partner Network since June 1st!
• 15 years of partnership with Google Cloud, Partner of the Year multiple times, and a premium partner ecosystem (AWS, Microsoft, Scaleway, S3NS, Databricks, Snowflake, Confluent, dbt…)
• 90+ active clients and 5,000+ people trained per year through SFEIR Institute

What all Sfeirians have in common is a passion for Tech.

Our culture is firmly oriented toward technological excellence, knowledge sharing, and our core values: kindness, diversity, excellence, freedom, and responsibility.

We are AI‑Powered: we use RAISE (our internal tool) and Claude Code on a daily basis. Our Anthropic partnership gives you access to tools and certifications before anyone else.

Community spirit is in our DNA: speakers at local meetups, monthly internal presentations, a community blog, and IC career paths to grow in expertise without leaving the code.

What we’re looking for

You’re not afraid to:

• Prompt and talk to LLMs like colleagues
• Juggle Python, FastAPI, LangChain or LiteLLM to integrate AI models
• Think architecture, orchestration, RAG, diffusion, FinOps and everything in between

You want to understand how it works – not just consume it.

Projects

• Build unified GenAI APIs (text, image, video, RAG) on Google Cloud
• Create specialized chatbots capable of 100% personalized recommendations
• Integrate GenAI platforms at our clients’ sites and tailor them to their context
• Design digital twins to model the real world

Bottom line: real work, not PoCs that end up collecting dust.

Brussels factor

SFEIR Belgium offers a startup vibe backed by a large group’s resources:

• A team of 10+ devs where everyone knows each other
• An Engineering Director (Renaud Hoyoux) who still codes alongside you
• Stylish offices on Avenue Louise
• A vibrant tech scene: internal talks, meetups, afterworks, and knowledge sharing
• The AI Champions program to level up with AI

What we offer

• Salary: Based on your real skills, validated at the PlayOffs – our technical recruitment process
• Company car or mobility budget
• Premium gear: MacBook Pro or Dell, your choice
• Pluxee meal vouchers and eco‑vouchers
• European phone plan
• Health insurance: DKV Hospi

Location: at our clients’ sites across the Brussels metropolitan area

• HR interview with Vanessa
• Technical pair‑programming tests (algorithm, language, platform)

Our process is a mutual discovery – you also get to decide whether we’re the right fit for you. We assess your reasoning, your way of collaborating, and how you unblock situations – well beyond what a CV can tell.
